Confectioners' sugar, cocoa, butter, milk and vanilla are cooked in a double boiler, then beaten like mad and spread in a pan to cool into fudgey gloriousness.
Butter a 9x9 inch dish.
Combine sugar, cocoa, butter, milk, vanilla and salt in the top of a double boiler over simmering water. Cook, stirring, until smooth. Remove from heat and beat until mixture loses its gloss. Stir in chopped nuts and pour quickly into prepared pan.
Let cool completely before cutting into squares.
